Emotionally Distress

I've been working at a new workplace and I felt itimidating by my coworkers. I'm new to this state and felt that there are alot of coniving people around here.Its a place of lots of competition in this area such materialistic. Mostly, the conversation when women around my workplace talks about it's brand name make-up, and diets. Appearance matters so much here. I don't connect with the people here. I'm not sure if it's my lack of social skill or just not my kind of topic I have no interest in joining their conversation. Additionally, we're decade apart.The main thing is that I don't feel assertive to speak my mind when issue arise and I felt helpness. I try to do positive self talk and practice assertiveness each time.I need to talk to others to let my feeling out and share my emotions. For someone to empathize for me and have similiar situation.
